Abstract
FOR the physiological analysis of plant growth, estimates of the total leaf area per plant are required, and this may involve the determination of the areas of large numbers of leaves. Freeman and Bolas1 have described a method for the construction of a measuring grid from which the areas of leaves may be read directly, providing that the leaf-shape approximates closely to an ellipse, as does the shape of the apple leaves used by them.
